Help text

This enables initialization of Qualcomm limits management hardware(LMh). LMh allows for hardware-enforced mitigation for cpus based on input from temperature and current sensors. On many newer Qualcomm SoCs LMh is configured in the firmware and this feature need not be enabled. However, on certain SoCs like sdm845 LMh has to be configured from kernel.
